Abstract

The finite element analysis method is used to simulate the mechanical behavior of packer rubber based on the virtual work principle, the Von Mises yield principle, and the contact nonlinear theory. The influences of working temperature, intermediate rubber hardness, and casing wall thickness on the sealing performance of packers were analyzed, and the contact stress distribution law between combined rubber and the casing wall under different conditions was obtained. The results show that: (1) as the temperature rises, the sealing performance of rubber tubes rises nonlinearly; (2) as the hardness of the intermediate rubber decreases, the sealing performance of the split rubber gradually increases, and the sealing performance is improved. (3) With the increase in casing wall thickness, the maximum contact stress between rubber tube and casing increases, and the sealing performance is improved.
